Notable projects include the first California digester at Van Warmerdam Dairy, operational since May 2013, and the Pixley Biogas project with Calgren Renewable Fuels, which offsets up to 4% of the natural gas used by an ethanol plant (source: maasenergy.com). The company has also developed the Stillwater Ranch project in Hanford, CA, which utilizes a virtual pipeline to deliver biogas as compressed natural gas (CNG) for vehicle fuel, and upgraded the Hilarides Dairy digester to enhance efficiency and reduce emissions (source: maasenergy.com).
